Thanks to Simply Research, we've covered prior authorizations and their denials in Colorado, but what happens when a prior authorization denial gets appealed?

Here's a look at the process in the Rocky Mountain State.

10-Day Rule

The requesting ATP shall have 10 days from the date of the written denial to submit an appeal with additional information to support the request.

The Payer shall have 10 days from the date of the appeal to issue a final decision and provide documentation of that decision to the Provider and parties.

Documentation

If the Payer is upholding a denial for medical reasons, the Payer shall have all the submitted documentation reviewed by a Provider.

Dispute Resolution

In the event of continued disagreement, the parties should follow dispute resolution and adjudication procedures available through the Division or the Office of Administrative Courts.

Expedited Hearings

An urgent need for Prior Authorization of health care services, as recommended in writing by an ATP, shall be deemed good cause for an expedited hearing.
